Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) enzymes, reducing prostaglandin synthesis, thereby exerting analgesic, anti-inflammatory, and antipyretic effects.
Non-selective cyclooxygenase (COX-1 and COX-2) inhibitor; reduces prostaglandin synthesis.
500 mg to 1000 mg orally initially, then 250 mg to 500 mg every 8 to 12 hours. Maximum daily dose: 1500 mg.
400-800 mg orally every 6-8 hours as needed; maximum 3200 mg/day.

Clinical Note
moderateDiflunisal + Trovafloxacin
"Diflunisal may increase the neuroexcitatory activities of Trovafloxacin."
The terminal elimination half-life is 2-4 hours in adults with normal renal function. In elderly patients or those with renal impairment, half-life may be prolonged up to 8-12 hours, requiring dose adjustment.
Renal (90% as glucuronide conjugates, <5% unchanged); biliary/fecal (<10%)
Renal excretion of unchanged drug accounts for approximately 70-90% of the administered dose, with the remainder eliminated as glucuronide conjugates in urine. Biliary/fecal elimination is minimal (<5%).
